Infant Nutrition and 12 and 18 Months Secure Base Behavior: An Exploratory Study

Latin American Attachment studies: A narrative review

Attachment theory´s core hypotheses (universality, normativity, sensitivity, and competence) are assumed to be applicable worldwide. However, the majority of studies on attachment theory have been conducted in Western countries, and the extent to which these core hypotheses are supported by research conducted in Latin America has never been systematically addressed. The purpose of this systematic narrative literature review is to provide an integrative discussion of the current body of empirical studies concerning attachment theory conducted in Latin American countries. For that purpose, a search was conducted in four electronic databases (Web of Science, PsycInfo, SciELO, and Redalyc) and 82 publications on attachment and/or sensitivity met inclusion criteria. None of the studies reported cases in which an attachment relationship was absent, and a predominance of secure attachment patterns was found, mainly for non-risk samples (NRS). Sensitivity levels were generally deemed adequate in NRS, and related to attachment quality. Attachment security and caregivers' sensitivity were positively associated with child outcomes. Attachment-based intervention studies mostly showed efficacy. In conclusion, Latin American research supports the key theoretical assumptions of attachment theory, mainly in samples of urban middle-class NRS. However, the field of attachment-related research would be enriched by also investing in Latin American studies on caregiving rooted in local concepts and theories.

Attachment theory's core hypotheses in rural Andean Peru

This is the first study aiming to test two universality claims of attachment theory within a rural Andean sample from Cusco, Peru. A total of 69 mothers and their children (6 to 36 months) participated. Child attachment security was assessed with the Attachment Q-set (AQS), maternal sensitivity was measured during three naturalistic episodes (free interaction, bathing, and feeding) with the Ainsworth sensitivity scale and the Maternal Behavior Q-sort (MBQS), and a cumulative maternal risk variable was calculated. Results revealed that most children displayed less characteristic secure base behaviors in the interactions with their mothers, compared to other reference samples. Furthermore, an association between maternal sensitivity and child attachment security was found, and a negative relation between maternal sensitivity and the cumulative risk variable. These results support some of the attachment theory's universality claims, and suggest new avenues for research on assessment issues in rural samples in the Global South.
